// According to Lenny Foner, Jim's camera is 2 seconds ahead of GPS time// this was also a 10 s exposure and the date was probably recorded at// the end of exposure (?)

truedate = exifdate - 2 s - 5 s

// We don't care all that much about refraction, so the temp/pressure figures// below may not be accurate but shouldn't matter much.
